Best 20A IEC power cord

It's been a while since this topic was covered in Audiogon. I have the Sierra Denali amps and the power cords are pretty loose fitting. That aside (I'm sure they would be replaced if I asked), I have a bit of an aversion for stock cords. BMI no longer makes the 20A version. Any other recommendations? Thanks in advance.

Ozfly,

I also own the Denali amps (2 used in monoblock configuration) on which I use a TG Audio HSR i2 power cord. They were my original 15A cords that Bob Crump reterminated with the 20A connector for $50.00ea including shipping. These power cords were recommended by Marty of Bound for Sound fame during his review of the Denali amp several months back. They are a very synergistic match with the Denalis. With that said, I am thinking about upgrading to the new TG Audio SLVR power cord (w/20A connector). Both cords list for $500/ea. Hope this helps.

Ozfly, From a very simplistic view, we can use the equation P=VI where Power = voltage times current. Using the Denali specs (from their Website) of 400W at idle and 2000W max, at idle I (current) = 3.44Amps and at the extreme, Imax = 17.24Amps. Granted this equation is used to calculate dc power, but it serves to show the worst case constant current draw from the Denalis. 17.24 amps is excessive and not very realisitic, so I would not be concerned with exceeding the 15A rated spec of the standard power cords. I agree with Sean that the bigger the wire gauge the better. I recall seeing a chart that list the wire gauge vs current carrying capability. The trend was the larger the wire size the higher current capability. Just my .02
